LIGHTING DEVICE.

Specification of Letters Patent.

Patented July 14, 1914;.

Application filed September 24, 1912. Serial No. 722,020.

To all whom it may concern Be it known that I, EDWARD J. MoRPHY, a citizen of the United States, residing at No. 123 Ford avenue, Barberton, Ohio,

have invented certain new and useful Improvements in Lighting Devices, of which the following is a specification.

This invention relates to improvements in lighting devices.

My improvements relate particularly to lighting devices of the class or type in which.

sparks are produced by the rubbing of a pyrophoric or other suitable material across an abrader.

The main ob]ect of this invention is to provide a lighting device which is simple in structure and operation and very durable in use, the parts subject to wear being readily renewed.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:

Figure I is a detail side elevation of a structure embodying the features of my invention, the member 1 being indicated in open position by dotted lines. Fig. II is a side elevation looking from left of Fig. I. Fig. III is a detail view partially in section in line corresponding to line 3-3 of Fig. II. Fig. IV is a detail section on line corresponding to line 4E of Fig. 11. Fig. V is a. detail view partially in section on line corresponding to line 55 of Fig. II.

In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing I provide a pair of pivoted members as 1 and 2 pivotally connected at 3. The members 1 and 2 are provided with handles 4: and 1. An A-shaped spring 5 is arranged between the members 1 and 2 below the pivot 3, one arm of the spring resting in the member 2 which is formed of sheet metal U-shaped in cross section the other arm of the spring resting against the member 1 and being held in position by the handle 4. See Fig. V. The member 1 is notched at 15 to receive the lug 16 at the end of the spring. '1 he'mcmber 2 is turned laterally at its outer end to provide a supporting arm 7 for the abrader.

The arm 7 is provi ed with a longitudinal slot 8. The abrader 10 is removably supported by the pin 9 arranged through the member 2 and the ear 7. The pin is secured by the cotter pin 9. The abrader 10 is cylindrical and crowned with a file like surface. The abrader 10* is held normally against rotation between the side of member 2 and the ear 7.

The member 1 is provided with a lateral offset 1 embracin the arm 7. The member 1 is preferably a rod and adapted to close into the member 2. Themember 2 is provided with ears 3 for the pivot 3, the member 1 being arranged between the cars as shown. The member 1 is provided with a holder 11, having a bore-like socket 11 therein. The holder 11 is mounted so as to overhang the arm 7. A block 12 of pyrophoric or other suitable material is arranged in the holder socket with its end through the slot 8 in the arm 7. The block is supported by the coiled spring 13 arranged in the socket 11, the spring being supported by the follower 14lthreaded into the outer end of the socket.

The handles 4: and a serve as stops to limit the opening movement. By removing the handle 1 the members can be swung so that the holder 11 clears the arm 7 to permit the insertion or removal of the block 12. By this simple arrangement the blocks can be renewed quickly and easily and at the same time are effectively supported. The handle 4 is preferably adapted as a holder for a supply of the blocks 12, the same being provided with removable cap 17. The abrader 10 can be renewed if desired, butthat is required only after long use as it may be adjusted so that its entire surface can be utilized.

My improved lighting device is simple in structure and operation. Owing to the block 12 being held in contact with the abrader by means of the spring 13 a good contact is maintained until the block is worn out. By adjusting the follower 14: the proper amount of friction pressure is secured.

Having thus described my invention, what I claim is new and desire ters Patent is 4 I 1. An igniting device comprisinga pair of pivoted members, one of, the membersbeing turned laterally and inwardly to provide an abrader supporting arm with an ear at to secure by Letits outer end, said arm being longitudinally slotted, the other member belng offset to embrace said arm; a pin removably arranged through said arm member'and' said ear; an

abrader mounted on said spin; a pyrophoric holder having a longitudinal bore-like socket therethrough mounted on theouter end of said offset to overhang said abrader supporting arm; a pyrophoric arranged in said holder to project into vthe slotin said abrader porting arm supporting arm to supporting spring for ,said pyrophoric; and a followerfor said spring threaded into the outer end of said holder. 3

2. A spark producing device comprising a pair of pivoted bers being provided with a laterally projecting longitudinally slotted abrader supat its outer end, the other mem her being ofisetto embrace said arm and having a holder at its outer end overhang ing 'saidar'm; an abrader rotatably mounted on sa1d arm; a block of spark producing materlal arranged through sald'slot 1n said armrand a supporting sprlng for said block.

3. A spark producingdevice comprisinga pair of pivoted "members, oneof said members being provided with a laterally projecting longitudinally slotted abrader supporting arm her being abrader mounted on said arm; a block of spark producing material arranged in said holder and extending through said slot to co-act With said abraderg and handles for said members adapted as stops to limit the opening ofthe members one of the handles being removable to permit the holder being swung clear of the abrader supporting arm for the removal or insertion of the block.

4. A spark producing device comprising a pair of pivoted members, one of said members belng provided witha laterally proj ectlng longitudinally slotted abrader supporting arm at its outer end, the other member Copies of this patent may' be obtained 01 five cents each, by addressing 'Vil'ashington,10.0.?
